Tadeusz Kossak (1 January 1857 in Paris – 3 July 1935 in Górki Wielkie), was born into a noted Polish family of artists and writers.
He was an officer in the Polish Army, a freedom fighter, and owner of a country estate in Górki Wielkie that became a hub for intellectuals of the era.
After the family's return to Congress Poland from his birthplace of France, Kossak attended school first in Warsaw and later in Kraków.
In 1922 with his wife Anna (née Kisielnicka), he moved from Kresy Wschodnie in Eastern Poland to Górki Wielkie near Cieszyn in Silesia.
There they leased from the state a country estate where they hosted many intellectuals of the period, including Jan Parandowski, Maria Dąbrowska, Jan Sztaudynger, Melchior Wańkowicz, Wojciech Kossak, Maria Pawlikowska-Jasnorzewska, Magdalena Samozwaniec, Jadwiga Witkiewicz, and her husband, Stanisław Ignacy Witkiewicz.
